From my other thread (http://forum.osnn.net/showthread.php?t=78869) I have determined its a virus. I decided to remove NAV 2003 and switch to AVG AntiVirus but when I restart I get a stop error that has to do with a buffer overrun by a driver. When I select Last Known Good Config the system boots fine but AVH cannot load the realtime scanner. I have determined its AVG messing up. While I was updating my friend's antivirus I decided to do my laptop and desktop BUT they both had the same stop error and the same solution worked to allow them to boot. I have switched to Avast AntiVirus which has no problem. I would prefer to use AVG but I cannot find a solution, I was hoping someone here would.
